Command line flag is effective:

  $ hg add a --config ui.exitcodemask=63
  abort: no repository found in '$TESTTMP' (.hg not found)!
  [63]

  $ HGPLAIN=1 hg add a --config ui.exitcodemask=63
  abort: no repository found in '$TESTTMP' (.hg not found)!
  [63]

Config files are ignored if HGPLAIN is set:

  $ setconfig ui.exitcodemask=31
  $ hg add a
  abort: no repository found in '$TESTTMP' (.hg not found)!
  [31]

  $ HGPLAIN=1 hg add a
  abort: no repository found in '$TESTTMP' (.hg not found)!
  [255]

But HGPLAINEXCEPT can override the behavior:

  $ HGPLAIN=1 HGPLAINEXCEPT=exitcode hg add a
  abort: no repository found in '$TESTTMP' (.hg not found)!

dispatch: add a config option to control exit code Summary: Previously, hg returns -1 (255) on "unknown errors". That could conflict with other things. For example, http://tldp.org/LDP/abs/html/exitcodes.html suggests 1, 2, 126 ... 255 have special meanings defined by a common shell. Namely, `ssh` also returns 255. Another long complaints about hg exit code is the use of 1 to indicate "no changes". Although that's explained at [1], a lot of scripts still find it surprising. This diff adds a `ui.exitcodemask` config option, which makes it to alter the exit code. Set it to 254 will change 1 to 0 for some script use-cases. Set it to 63 or so will avoid conflicts with software like `ssh`. Many existing scripts still expect 255 to be the return code. So we cannot change the default value that easily. To avoid surprises (like, put the config option in `/etc/mercurial/hgrc.d/exitcode.rc`), the config set by config files is ignored if `HGPLAIN` is set and `HGPLAINEXCEPT` does not contain `exitcode`.
