f592768d3a Remove the New flag from a buffer after reloading it 
If we reload a buffer, it means its underlying file exists, hence the
New flag does not make sense anymore. It could be that the file appeared
on the filesystem in the meantime.

81eb2ee428 Do not strip whitespaces with '*' 
Stripping whitespaces there is a failed experiment as it breaks the
ability to use multi-selections consistently: Using '*' followed by some
`N` to add following matches, we end up with mismatched selections
due to whitespace stripping the original selection still contains
whitespaces where all the new ones do not. Once we get to this state,
most selection commands will give different results for the initial
selection and the other ones, breaking predictible multiselection use,
one of the cornerstones of Kakoune editing model.

bf73cb0109 Reset normal mode before hiding the reload buffer info box 
Reseting normal mode will enable normal mode, which will trigger
a check for buffer modification. We do not want that check to
happen as we are trying to close the info box. Doing that mode
reset first will prevent the check from happening (as the info
box is already displayed), and will correctly hide it afterwards.

29a7cd3ab4 Insert complete: Remove path info with one buffer 
This change is useful when using `set scope completers word=buffer`,
instead of the default word=all.

If candidates all come from the same buffer, then the path/filename
information is the same and therefore unnecessary. This change
prevents the same path from being repeated, and the buffer's
source code is less obscured.

More generally, there could be an option to disable the path
information entirely in all cases, but for now this change seems
a reasonable solution until any such option exists.

299e22ca7c Do not block when waiting for next event if we have pending input 
Handle next event should never block if we have already accumulated
input that we want to process. As we can accumulate new input in
lots of places (everytime we run a shell process for example, we
might end up reading input keys. That can be triggered during the
mode line generation which takes place during display of the window)

e74b581b0a Save/restore main selection from/to strings 
Always consider that the first selection in the list is the main
one, save selections that way.

This approach was suggested by PR #1786 but the implementation here
is different, and is used more generally whenever we save selections
to strings.

This is also the prefered way to work only on the main selection:
save selections with Z, reduce to main with <space>, restore with z.

18a02ccacd Regex: Optimize parsing and compilation 
AstNodes are now POD, stored in a single vector, accessed through
their index. The children list is implicit, with nodes storing only
the node index at which their child graph ends.

That makes reverse iteration slower, but that is only used for reverse
matching regex, which are uncommon. In the general case compilation
is now faster.

d9b4076e3c Regex: Go back to instruction based search of next start 
The previous method, which was a bit faster in the general use case,
can hit some cases where we get quadratic behaviour and very slow
matching.

By using an instruction, we can guarantee our complexity of O(N*M)
as we will never have more than N threads (N being the instruction
count) and we run the threads once per codepoint in the subject
string.

That slows down the general case slightly, but ensure we dont have
pathological cases.

This new version is much faster than the previous instruction based
search because it does not use a plain `.*` searcher, but a specific,
smarter instruction specialized for finding the next start if we are
in the correct conditions.
