-- [x] add checking for conflicting command-line options
+- [ ] add checking for conflicting command-line options
+- [ ] support for deletion of messages after being matched and displayed
 - [x] ignore .overview when grepping Gnus folders
 - [x] inverted matching
 - [x] recursive search through directories
 - [x] writing selected messages to a new folder
 - [x] deleting selected messages
+- [ ] basic time and date matching
+- [ ] more advanced time and date matching, with strings such as "yesterday"

-- [ ] basic time and date matching
-- [ ] more advanced time and date matching, with strings such as "yesterday"
-- [ ] Remove the option to recursively traverse directories and instruct the users to run mboxgrep in conjuction with find(1) instead.
 
 ## File formats, encodings and standards
 
-- [x] migrate to pcre2, as pcre is obsolete
-- [x] support for compressed mbox folders
-- [x] support for bzip2 compression
-- [ ] use a more modern hash function than MD5
 - [ ] MIME support

 ## Miscellaneous
 
 - [x] write Texinfo documentation

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.
