External commands lead to cryptic failure instead of readable error message
As discussed in #32 (closed), external commands are not supported during parsing as $PATH
is invalid.
This sounds reasonable, though an explicit error message would be appropriate too.
I'm thinking something with a tag like external-commands
:
bluespec-git E: References external commands (commands [pacman, cut, awk] in PKGBUILD)
If necessary, the message can then be looked up in the ArchWiki (once it's added there)
