From 78cfa00154dca18a1326d2064121bf65cd081781 Mon Sep 17 00:00:00 2001 From: Ron Yorston Date: Sun, 19 Jul 2015 21:41:09 +0100 Subject: [PATCH] less: correctly account for tabs when rewrapping lines Lines are rewrapped when the terminal width changes or line numbers are enabled/disabled. The current calculation always adds eight to the line length for a tab whereas it should only add enough to move to the next tab stop. This doesn't affect the display of lines, which is handled elsewhere and gets tab stops right, but it does cause lines to be wrapped at the wrong position.
