zsh_completion: update some option usage flags ('+', '=' and ':')

Here are the relevant symbol descriptions from [0]

optspec:...
  The colon indicates handling for one or more arguments to the option; if it
  is not present, the option is assumed to take no arguments.

-optname+
  The first argument may appear immediately after optname in the same word,
  or may appear as a separate word after the option. For example, ‘-foo+:...’
  specifies that the completed option and argument will look like either
  ‘-fooarg’ or ‘-foo arg’.

-optname=
  The argument may appear as the next word, or in same word as the option
  name provided that it is separated from it by an equals sign, for example
  ‘-foo=arg’ or ‘-foo arg’.

There are 3 types of changes in this patch:

- addition of '=': means that '--repository ~/foo' can now also be spelled as
  '--reporitory=~/foo'

- addition of '+': means '-r 0' can now also be spelled as '-r0'

- removal of '+', '=' and ':': means that '-u|--untrusted' doesn't take any
  arguments, so '-uq' is definitely '-u -q' and not '--untrusted=q'

Occasionally, ':' had to be added together with '=' and '+'.

This patch is mostly just making zsh_completion file look more like zsh's own
hg completion file so that we can more easily take improvements from them or
send patches to them. Some context for this patch from zsh project: [2] [3].
