Subject: Bug 1137, handle single-digit runways.
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=ebfe2ee6f501a19f4a96f8c5fb59e6207e51d70a;p=flightgear.git

Bug 1137, handle single-digit runways.

rwyprefs.xml sometimes specify runways without a leading '0', which
confuses the ident lookup. Print a message, and fix up such idents at
load time, so '8' -> '08', '3L' -> '03L' which matches our internal
scheme.
