[Vimprobable-users] [PATCH REROLL 1/1] Saner config file checking.

[Thomas Adam]

Don't moan if RCFILE cannot be opened -- instead, use give_feedback() if an
explicit config file was passed on the command-line, but couldn't be opened.
For everything else, use an explicit error, because we assume the file
could be opened, but not parsed for some reason.

 This appears to have fallen through the cracks...
 Have updated it to sit atop of 0.9.20.

 I broke this by mistake when I introduced "-c" on the command line.
