[PATCH 3/3 (alternate)] gitweb: Mark "atnight" author/committer times also for 'localtime'

[Jakub Narebski <jnareb@gmail.com>]

From: Kevin Cernekee <cernekee@gmail.com>

By default, with 'localtime' feature disabled, the dates in 'commit',
'commitdiff' and 'tag' views show both GMT time, and localtime in
recorded author/committer/tagger timezone, marking localtime with
"atnight" class to notify times between 0 and 6 AM local time.

An example output can look like this:

  author   A U Thor <author@example.com>
           Wed, 16 Mar 2011 07:02:42 +0000 (02:02 -0500)
                                            ^^^^^

where underlined part is marked with "atnight" class (in red with
default stylesheet).

If $feature{'localtime'} is enabled, we display the RFC 2822 date/time
in the author's/committer's/tagger's local timezone; previous commit
removed marking "atnight" times, because there wasn't separate local
time to mark up after GMT time.

This commit makes gitweb mark _whole_ RFC 2822 date/time with
"atnight" class for times between 0 and 6 AM.

An example output can look like this:

  author   A U Thor <author@example.com>
           Wed, 16 Mar 2011 02:02:42 -0500
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

where again underlined part is marked with "atnight".

We probably should mark only time part of RFC 2822 date/time with
"atnight" class, but such solution would be more involved.

While at it fix whitespace, using spaces for align, tabs for indent.


NOTE that git_print_authorship subroutine is for now left as is; there
is no caller in gitweb that uses it with -localtime=>1.

Kevin, how about something like this instead?  This preserves _intent_
for why there is local time beside GMT time when 'localtime' is disabled
better, I think.

Junio and Kevin, I am not sure if authorship should remain with Kevin,
or should it revert to me; the solution is quite different.

About no-change to git_print_authorship: alternate solution would be
to remove support for -localtime option, like in original patches.
