minirst: update module docstring

commands: use enumerated lists in help texts

minirst: support enumerated lists

minirst: prepare for general types of bullet lists The old code worked for '-' bullets only, but we can easily support variable width bullets.

minirst: combine list parsing in one function Bullet, option, field, and definition lists were parsed very similar code. They are now parsed by a single function (splitparagraphs). Some logic from the old parsing functions has been moved down to formatblock. This simplifies the parsing while putting the logic where it's really needed.

test-minirst: don't test on invalid reST input Input such as Only the left-most line (this line!) is significant for the indentation is not valid reStructuredText: the first line starts a block quote, but then the second line is not allowed to be unindented.

minirst: remove unnecessary "elif:" statements

commands: call ui.username carefully in debuginstall After c63c336ee2f7, 'hg debuginstall' would abort halfway through if no username was set. We now catch and display the exception instead.

mq: do not call ui.username unless it is necessary After changeset c63c336ee2f7, ui.username will abort by default if no username is set. It is therefore wrong to call ui.username when a username was provided on the command line.

util: sort paths in walkrepos() (fixes test failures in test-hgwebdir)
