The commands grep and file-query-replace, when applied to buffers instead of to files, now understand simple wildcard characters like *, ?, and [a-z] in the buffer specification. To make these commands operate on buffers instead of on files, give the command a numeric argument.
Grep now skips over files with certain extensions: .o, .b, .obj, .exe, and so forth. Set the grep-ignore-file-extensions variable to modify this list.
The grep and file-query-replace commands now interpret relative file patterns based on the directory of the current file. To get the previous behavior, set the grep-prompt-with-buffer-directory variable to zero.
When you halt a file-query-replace by pressing <Period> or <Escape> (and not just when you abort it), Epsilon asks if you want to continue to replace in the remaining files.
