[PATCH 7/8] common/parser.c: Do not conflate error reporting disciplines

[Andrey Smirnov]

Run_command() uses 0 to indicate success and negative values to
indicate errors, whereas execute_command() uses 0 for success and
positive integers to represent error codes. Conflating the two breaks
the code that calls run_command and then checks for error code sign to
detect problems, so avoid that by doing a very simple transformation
on the result of execute_command
