Update to 6.2.9:

Version 6.2.9 - August 26 2013

[CHANGES]
New facilities:
o configure: New option --with-sitekeys-mode=MODE.

Changed:
o jquery.treeview.js: Removed effects on mouse over because they use time too much
  to build a tree. Now it works faster than previous versions.
o htags: Added a loading message when the --tree-view option is specified.

[INCOMPATIBLE CHANGES]
o gtags-cscope: Though previous gtags-cscope ignored GTAGSROOT, GTAGSDBPATH when
  the -d option was not specified, it was meaningless. Now it accepts both of them
  always.

[BUG FIXED]
o gtags-cscope: Arrow keys didn't work after execution of external programs. Now \ 
it works.
o global: The -u option didn't work in a project whose path includes blanks. Now \ 
it works.
o htags: Fixed some bugs about --tree-view option.
- The type argument of --tree-view option didn't work in the top page. Now it works.
- Directory icons by --tree-view=filetree were not displayed. Now it works.
- On-line manual didn't say about the type argument. Now it is written.
