Have you considered if it may be helpful to have a :(literal) magic
(or any magic in general) that applies only to the first N
characters of the pathspec pattern?
When you are in subdirectory and do a pathspec limited operation,
cd Documentation && git ls-files "*.txt"
we internaly do an equivalent of this:
(1) first find out the "prefix", e.g. "Documentation/" in this
(2) prepend the prefix to user-supplied pathspecs, e.g. yielding
"Documentation/*.txt" in this case; and
(3) use the resulting pathspecs to match against full pathnames
relative to the root of the working tree.
If the prefix had globbing character in it (e.g. we started in a
directory "D*cumentati*n" instead), we still should make sure that
that part matches literally, while allowing the globbing in
user-supplied part of the pathspec (e.g. "*.txt"). In the built in
code, you can work with the struct pathspec directly and mark the
entire prefix part with nowildcard_len field to match literally, but
if the above three-step logic needs to be implemented by a Porcelain
script like old days, they would need to quote glob specials in the
prefix part before appending user-supplied part to form the full
I personally think we do not need to support something like this:
prefix=$(git rev-parse --show-prefix)
but other aspiring Porcelain script writers may disagree and would
want to have it. We can always solve it by giving them an easy and
uniform way to get the glob-quoted version of prefix to solve this
particular issue, i.e.
prefixq=$(git rev-parse --show-prefix-glob-quoted)
but magic that applies only to a substring may have other uses.
If you do not immediately think of any, let's not overengineer this.
