I had particular issues when using "del" or "del x" where x is a
breakpoint.  I found several memory issues.

The debugger reparses breakpoint responses from gdb/MI. In
Modules/Debuggers/ProjectCenter/GDBWrapper.m:371, parseStringLine: parses
MI records.

A pity ju always go alone and never coordinate.. but it is what it is.

Understood.

Tabs were being handled inconsistently.  When using an actual "/t"
character, it would not indent properly.  Things that would display
properly in Emacs were not displaying correctly in ProjectCenter.  Part of
the issue was the editor did not set a paragraph style/default tab interval
for the text view. So real tab characters were rendered using the text
system=E2=80=99s default tab stops, while ProjectCenter=E2=80=99s ruler/col=
umn logic assumed
fixed-width editor columns.

The change I made added an 8-character tab interval based on the editor
font width in Modules/Editors/ProjectCenter/PCEditorView.m:538, then
applied it to typing attributes and existing text.

In short, tabs were NOT fine. :). The reason you are likely not seeing this
is that if you solely use PC then you're not using any other characters for
tabs.  This is why you're not seeing the same issues I am.

That's cool.  I have been less inclined to use it (PC) mainly because of
the debugger and the editor issue I mentioned above.  After these changes I
am finding it more difficult to resist. ;)
