Ubuntu 20.04 ships GCC's libstdc++ 10 from 2020 which implements
std::to_chars() for integers but not for floats. Use the float overload
only if the library advertises support via the feature testing macro.
This can be removed once we require GCC 11 (see
https://www.gnu.org/software/gcc/gcc-11/changes.html).
Closes#4607
Merge all lookarounds into the same instruction, merge splits, merge
literal ignore case with literal...
Besides reducing the amount of almost duplicated code, this improves
performance by reducing pressure on the (often failing) branch target
prediction for instruction dispatching by moving branches into the
instruction code themselves where they are more likely to be well
predicted.
When trimming indent, the last line, if only containing
whitespaces does not need to match the indent, so that
this indentation style works:
-docstring %{
indented string
}
This commit implements formatting behaviour when the first character of a
docstring is a newline. In that case, the exact indentation level of the
next line will be removed from that line and all subsequent non-empty lines.
An error will be returned if a subsequent non-empty line does not have the
same indentation level.
The docstrings are always trimmed (surrounding whitespaces) whether the
first character is a newline or not, as was the case prior to this commit.
Example: the following declaration
```
define-command test -docstring %{
test: do something
Nothing really.
More
indented
lines.
} nop
```
would be rendered as
```
test: do something
Nothing really.
More
indented
lines.
```

Do not allocate temporary vectors to store splitted data, use the
'split' range adaptor along with transform(unescape) to provide the
same feature with less allocations.
