We add a magic line to the beginning of each Makefile.local file to
help the editor know that it should use makefile mode for editing the
file, (even though the filename isn't exactly "Makefile").
Edited-by: Carl Worth <cworth@cworth.org>: Expand treatment from
emacs/Makefile.local to each instance of Makefile.local.
We currently allow the cursor to be positioned on the "End of search
results" line after the last thread in a search buffer. When
refreshing on this line, there's no thread ID to be used as the
target.
Previously, a refresh from this case would result in a nil thread
target, but we were also using nil to indicate that the target thread
had been found. This caused the position to be lost during refresh,
(the cursor would move from the last line in the buffer to the first).
We fix this by using a magic string of "found" rather than nil to
clearly indicate whether the target thread has actually been found.
It doesn't make sense to move the cursor to some random point in the
middle of a line. We always want the refresh to leave the cursor at
the beginning of some line instead.
We were previously maintaining two lists of the child Makefile
fragments---one for the includes and another for the dependencies. So,
of course, they drifted and the dependency list wasn't up to date.
We fix this by adding a single subdirs variable, and then using GNU
Makefile substitution to generate both the include and the dependency
lists.
Some side effect of this change caused the '=' assignment of the dir
variable to not work anymore. I'm not sure why that is, but using ':='
makes sense here and fixes the problem.
Add emacs/Makefile.local and emacs/Makefile. Move emacs targets into
emacs/Makefile.local, but leave the byte compilation rule in the top
level Makefile.
