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.
