Re: [External] : Re: Adding refactoring capabilities to Emacs

[Alfred M. Szmidt]

To wit, the difference Dimitry is raising is:

C-x C-f ~/RMAIL RET                     Opens ~/RMAIL in Fundamental mode
C-x C-f ~/emacs-build.gcov RET          Opens file in Compilation-mode

vs.

M-x rmail RET                           Opens ~/RMAIL using the RMAIL "program"
M-x compile RET make RET                .. similar

The two later, the thing you are working is by "dedicated mode"; the
first ones you are working with the file in the specific mode.  This
is similar to diff, occur, etc.  The issue is that sometimes, a mode
might want more or less .. RMAIL is a good example where it wants
more.
