Thanks for reporting this.
A different way to interpret the situation is that the user-interface
is being inconsistent. For instance, the "fields" pop-up next to the
"exact/ignore-case/regexp" pop-up does not seem to make sense for
search types other than "containing", so it probably ought to be
disabled for anything other than "containing". By extension, one could
argue that the "exact/ignore-case/regexp" pop-up also ought be
disabled for non-"containing" searches. The fact that they are not
disabled confuses people into thinking that they should be functional
for all searches, not just for "containing" searches, even though such
functionality was never implemented (and indeed, may be difficult to
implement fully).
Your proposed fix handles only the "ignore case" item; it does not
implement "regexp" functionality, so it could be considered
incomplete. A more complete fix would also disable the "regexp" item
to avoid misleading users, and to head off future bug reports similar
to this one saying that "regexp" doesn't work for non-"containing"
searches. (Bonus points for also disabling the "fields" pop-up for
non-"containing" searches when it's not applicable.)
Below is your fix wrapped up as a proper patch and sent in-line rather
than as an attachment. It's also slightly simplified by dropping the
unnecessary extra variable. You'll need to sign-off on the patch if it
is ever to be accepted. You can do so by adding it after my sign-off.
If you don't feel like re-sending the patch with your sign-off, you
can alternately reply to this email with a "Signed-off-by: Your Name
<your@email>" line.
Note, however, that the gitk project is, at best, deeply slumbering,
so it's not clear when or even if patches will be incorporated.
(Indeed, other recent gitk-related patches sent to the mailing list
have not yet been picked up.)

Subject: [PATCH] gitk: support "ignore case" for non-"containing" searches
The "Exact/Ignore Case/Regexp" pop-up control only affects "containing"
searches. Other types of searches ("touching paths", "adding/removing
strings", "changing lines matching") ignore this option. Improve the
user experience by also recognizing "ignore case" for non-"containing"
searches.
Note: This change only implements the "ignore case" option for these
other search types; it does not add support for the "regexp" option
(which still only affects "containing" searches). A more complete "fix"
would improve the user experience even more by making the UI more
consistent; namely, by disabling options which don't make sense or are
not easily implemented for non-"containing" searches. In particular, the
"regexp" pop-up item and the neighboring "fields" pop-up control ought
perhaps be disabled when a non-"containing" search is selected.
