Make hgk handle filenames with spaces (issue49)

Use "--config ui.report_untrusted=false" for hg calls in hgk, fixes issue523. tcl's exec yields an error if output to stderr happens and isn't redirected to a file, so the warnings about untrusted .hg/hgrc caused problems in hgk. The warning is still printed when executing 'hg view', so the user can see it when using it from the shell.

Added full URL to debug output if something doesn't look like an http hg repo. This way it is easier to debug problems with failing subcommands, like changegroupsubset due to permission problems, when generally accessing the repository works fine.

Handle extensions with defined but empty cmdtable

mq: more qdelete help text tweaks

mq: require patch argument or revision for qdelete

Make hg glog abort if unused arguments are given.

Abort if earlygetopt fails to detect an option. Otherwise it could happen that a command is used on the wrong repository, because abbreviations of --cwd or --repository were ignored.

Simplified earlygetopt and made it remove parsed options and values. The order of aliases is no longer important, too.

Disallow short earlygetop option combined with other short options While "hg commit -qRfoo" can be read as "--quiet --repository foo", "hg commit -mRfoo" should be "--message Rfoo".
