commands: wrap short descriptions in 'hg help'

The code for wrapping a single line of text with a hanging indent was
duplicated in commands and help -- it's now moved to a new function
called wrap in util.

The function defaults to a line width is 78 chars, and this un-wraps
some command line flag descriptions, hence the test output changes.
