Due to ambiguity in the POSIX standard, GNU and BSD versions of the `wc`
utility use slightly different whitespace conventions when formatting
their output [1]. When limiting the output to just counting the number
of bytes (as is done by Kakoune when calculating the length of words
for spell check highlighting), the BSD version of `wc -c` has some
additional leading whitespace:
gnu$ printf %s "test" | wc -c
4
bsd$ printf %s "test" | wc -c
4
This leading whitespace needs to be removed before defining the "region"
to highlight, or `set-option` will not be able to parse the given
`spell_regions` and will complain that there are "not enough elements
in tuple." In other words, the region `1.21+8|Error` on Linux ends up
looking like `1.21+ 8|Error` on macOS, which is invalid.
Removing the whitespace could be accomplished in a number of ways, but
using arithmetic expansion [2] is POSIX compliant and does not require
shelling out to another process.

Fixup ctags-complete command to search for partial matches for the
current selection in all tags files listed in ctagsfiles option. Format
the results to fit the Kakoune completions type.
Add ctags-enable-autocomplete and ctags-disable-autocomplete commands to
add and remove an InsertIdle hook to select the previous word and call
ctags-complete.
Use the ctags_min_chars option to limit the noise of returning many
completions for very short selections.

Indentation can be different depending on the first word of list forms. The
indent hook uses `e` from inside the parent to select the first word for
testing whether it is a special word; however, in the case of a one-character
symbol, this selects to the end of the *next* word.
This rejects such selections.
