Subject: Fix display of VT100 vertically-offset horizontal line characters
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/putty/commitdiff_plain/3cb37e024bb69171703f0fe05cf6b131008f8460?ds=sidebyside

Fix display of VT100 vertically-offset horizontal line characters
(o,p,r,s). They are displayed in Windows by actually writing the
centred one (q) with a vertical offset, in case fonts don't have the
offset versions; this requires terminal.c to separate those characters
into distinct calls to do_text(). Unfortunately, it was only breaking
up a text-drawing call _before_ one of those characters, not after
one. Spotted by Robert de Bath.
