Subject: Print correct order for include order/style issues
X-Git-Url: http://biod.pnpi.spb.ru/gitweb/?a=commitdiff_plain;h=5d5989824b51611a3010eca8171791563767ada1;p=alexxy%2Fgromacs.git

Print correct order for include order/style issues

Make the 'check-source' target print the correct/conforming include
order together with the "include order/style is not consistent" message,
and add a reference to related documentation.  This hopefully makes
these messages easier to understand.
