setup: update runcmd() to also return the exit status Update the runcmd() helper function so it also returns the process exit status. This allows callers to more definitively determine if a command failed, rather than testing only for the presence of data on stderr. I don't expect this to have any behavioral changes for now: the commands invoked by setup generally should print data on stderr if and only if they failed.

Mercurial
=========

Mercurial is a fast, easy to use, distributed revision control tool
for software developers.

Basic install:

$ make # see install targets
$ make install # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg # see help

Running without installing:

$ make local # build for inplace usage
$ ./hg --version # should show the latest version

See https://mercurial-scm.org/ for detailed installation
instructions, platform-specific notes, and Mercurial user information.
