Subject: [tab_stop.pl] Implement tab stops with configurable length
X-Git-Url: http://git.99rst.org/?a=commitdiff_plain;h=71b7dabac851e7e56def1681ddad41f849e38ceb;p=irssi-scripts.irssi.org.git

[tab_stop.pl] Implement tab stops with configurable length

This changes the default behaviour to make TAB replacements line up.
To get the original behaviour, the user will need to do `/set
tabstop_interval 0` explicitly.
