Subject: Use the list of builtin functions for inlining.
X-Git-Url: https://git.stderr.nl/gitweb?p=matthijs%2Fmaster-project%2Fc%CE%BBash.git;a=commitdiff_plain;h=85bbc8126e1a7c8703d99afe3678ad067ca773a8

Use the list of builtin functions for inlining.

Previously a small, fixed list of functions was used for inlining. Now
we use the full list of builtin functions instead.
