Hey Richard,
Using your test case, I still get the error (which is, specifically an
error dialog saying:
Failed to stage selected line.
error: patch failed: glacierupload.sh:55
error:glacierupload.sh: patch does not apply
Note that I'm highlighting the change in the source code, then
right-clicking it and selecting "Stage lines for commit." ("Stage hunk for
commit" also results in the error.)
If I stage the entire file by clicking on it in the upper-lefthand pane,
things work fine.
This is a Gentoo box, so I wonder I happened to build Tcl without the
appropriate unicode support (that one would find in most package-based
distros)?
In briefly digging a bit more, it would seem that git gui is foisting the
work onto "git apply" to create a patch and stage it? (If I'm reading the
source correctly, It looks like the error dialog title is from
https://github.com/prati0100/git-gui/blob/master/lib/diff.tcl#L700
and then the error strings that populate the dialog are bubbled up from git
apply.
Any ideas on what would make "git apply" potentially choke? I wonder if it
has to do with a mixed file encoding?
I tried setting both:
core.checkRoundTripEncoding true
gui.encoding utf-8
on that repo; git gui still errored out in the same way.
I also tried changing gui.encoding to utf-16; no dice...
To reiterate, git add -i worked fine...
best,
preed

If I then use Fork's ability to Stage chunks of text containing these (or possibly not containing, but close after) I get this failure reported.
