mcedit: use Office/Word-style tab markers

[jengelh]

Suggestion:

Also among the tickets copied from Savannah was a suggestion to reduce the <------> clutter highlight_tabs makes. To that end I had written a patch to simply place tab markers similar to those shown in contemporary document editors in office suites - single arrow in the middle of the space taken up by the tab.

Did you try your patch on 7-bit and 8-bit locales?

i don't like that, because if there are spaces around the tabs and you don't have general whitespace visualisation enabled, you essentially have to guess where the tabs actually are, which is counterproductive for the goal of this feature (producing clean tabbing).

[angel_il]

now 'tab' drawn as 3 parts:
start - char '<'
middle - char '-'
end - char '>'

currently '<', '-', '>' is hardcoded chars
if these characters are defined in your skin we do not need change 'edit_draw_this_line'...

for example:
current behaviour

[widget-editor]
    start-sign-tab=<
    middle-sign-tab=-
    end-sign-tab=>

like this ticket

[widget-editor]
    start-sign-tab=' '
    middle-sign-tab=' '
    end-sign-tab=→

invisible tabs

[widget-editor]
    start-sign-tab=' '
    middle-sign-tab=' '
    end-sign-tab=' '

???
PROFIT

Then, please,

tab-first-char
tab-middle-char
tab-last-char

not "sign" "start" "end", but "character" "first" "last"
