- We do not write the noiseword "function" in front of shell

- As to use of grep, stick to a subset of BRE (namely, no \{m,n\},

* Building and installing with an overtight umask such as 077 made
installed templates unreadable by others, while the rest of the install

* "git send-email" in 1.5.4.3 issued a bogus empty In-Reply-To: header.
* "git bisect" showed mysterious "won't bisect on seeked tree" error message.
This was leftover from Cogito days to prevent "bisect" starting from a
cg-seeked state. We still keep the Cogito safety, but running "git bisect
start" when another bisect was in effect will clean up and start over.
* "git push" with an explicit PATH to receive-pack did not quite work if
receive-pack was not on usual PATH. We earlier fixed the same issue
with "git fetch" and upload-pack, but somehow forgot to do so in the
other direction.
* git-gui's info dialog was not displayed correctly when the user tries
to commit nothing (i.e. without staging anything).
* "git revert" did not properly fail when attempting to run with a
dirty index.
Also included are a handful documentation updates.
