A simple script that uses 'git ls-files' and xargs to
search and replace all the specified files.
---
Not meant for inclusion, just a simple script I wrote up
when I wanted to change a function name in my repository
but didn't want to figure out which magic argument to find
does what I want. Another advantage of using git ls-files
is that it will prevent that any unrevertable changes will
be made (since the script checks if the tree is dirty or
not). I'm sure there's plenty of room for improvement here,
it's probably not portable at all either, so comments are
welcome :).
