Subject: No more global-scoped functions or variables.
X-Git-Tag: bedstead-002.000~117
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~bjharris/git?a=commitdiff_plain;h=d67fd2c69201e0110818664e0ba68ef874b1f552;p=bedstead.git

No more global-scoped functions or variables.

Apart from main(), of course.  Everything else is now file-scoped at
most.  This is more consistent, and might allow for more
optimisations (if I ever used -O).
