That's fair, especially because it would be inconsistent with shell
command language, where single-quote inside double quotes is not
special:
$ printf '%s\n' "\'"
\'
(I realize that backslash means something different in Git config; I'm
just saying it would be another source of cognitive dissonance.)
Updated proposal:
1. Treat strings starting or ending with single-quote as worth
quoting in config.c::write_pair (line 3269). This would already
help with the original issue, since the config would say
[foo]
bar = "'baz'"
allowing a quick diagnosis.
2. (optional) Warn if a value is surrounded in single-quotes,
encouraging using surrounding double-quotes to disambiguate.
3. (optional) Error out if a value is surrounded in single-quotes,
encouraging replacing with or surrounding with double-quote,
depending on the user's intention.
4. (optional) Start treating wrapping single-quotes specially
somehow.
As before, I think step 1 is a good idea, but I'm not convinced about
any of the later steps.
Thanks,
Jonathan
