[arch-general] [PATCH 10/48] Replace trivial use of grep with bash regex conditional.

[Victor Lowther]

Bash has regex support, and it allows us to replace most trivial
uses of sed, grep, and awk.  The fewer processes we create, the faster
we go, and every little bit helps.

I also think it is more readable to use a bash regex for the trivial stuff.
