builddeb: add distroseries to tagged versions This is needed so that launchpad and friends have a unique version number for each distroseries (trusty, wily, xenial, etc). It was discovered when trying to upload 3.8 to launchpad.

debian: forgot to make debian/rules executable in 6b95a623ec90

debian: add wish to suggests Debian maintainers already have this and lintian warns us about not listing 'wish' as a dependency or suggestion so this patch does indeed just that. The issue, by the way, is that we are shipping hgk (which is written in tcl/tk) so we should be good citizens and list wish (a meta package for tcl/tk) as a dependency.

hg-ssh: copy doc string to man page This corrects a warning from lintian that we're shipping an executable without a man page. Since there is a doc string in the text, let's use that for the man page.

progress: stop excessive clearing (issue4801) The progress bar was being cleared on every write(), regardless of whether it was currently displayed. This could foul up the display of any writes that didn't include a linebreak. In particular, the win32 mode of the color extension was turning single prompt string writes into two writes, and the resulting clear/write/clear/write pattern was making the prompt invisible. We fix this by insisting that we have shown a progress bar and haven't just cleared it (setting lastprint to 0). Conveniently, the test suite already had instances of duplicate clears.. that are now cleared up.

chgserver: remove _clearenvaliases Since we expand environment variables in alias lazily, the _clearenvaliases hack is no longer necessary. This resolves an issue that a non-shell alias which has environment variables in its arguments and is set to use pager will not use pager running with chg.
