hgk: enable selected patch text on Windows Port a patch from gitk. Original description: On windows, mouse input follows the keyboard focus, so to allow selecting text from the patch canvas we must not shift focus back to the top level. This change has no negative impact on X, so we don't explicitly test for Win32 on this change. This provides similar selection capability as already available using X-Windows.

hgk: ignore ctrl-z as EOF on windows Port a patch from gitk. Original description: Cygwin's Tcl is configured to honor any occurence of ctrl-z as an end-of-file marker, while some commits in the git repository and possibly elsewhere include that character in the commit comment. This causes gitk ignore commit history following such a comment and incorrect graphs. This change affects only Windows as Tcl on other platforms already has eofchar == {}. This fixes problems noted by me and by Ray Lehtiniemi, and the fix was suggested by Shawn Pierce. Signed-off-by: Mark Levedahl <mdl123@verizon.net> Signed-off-by: Paul Mackerras <paulus@samba.org>

graphmod: changed code in dagwalker to use lazy implementations Used lazy methods when possible.

webcommands: changed code to use lazy classes when calling dagwalker This needs to be changed to use a baseset since dagwalker now expects to receive a smartset. This is basically wrapping revs into a baseset to be compatible with smartset implementations.
