GNU ed
GNU ed is an 8-bit clean implementation of the POSIX line-oriented text editor. Ed is the "standard" text editor in the sense that it is the original editor for Unix, and thus widely available. For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.

Quote characters in messages have been changed as advised by GNU Coding Standards. The description of address offsets in the manual and a link to the Bash manual have been fixed. The configure option "--datadir" has been renamed to "--datarootdir" to follow GNU Standards. The target "install-bin" has been added to the Makefile.

The "modified" flag is now set when reading a non-empty file into an empty buffer. An error that prevented using NUL characters in regular expressions has been fixed. Ed now signals an error if it can't create a shell process when executing a shell command. Ed now flushes stdout/stderr before reading a new command. All command-line options are now documented in the man page.

Really good editor for Unix
don't be so self deprecating!
Maybe the about section shouldn't be so self deprecating.
There are many good reasons still to have a decent line editor available on all systems. Some of those could be described instead of worrying about the other tools that don't really compare.
Re: errors in ed-0.4

Both errors will be fixed in version 0.6.
Next time, please use the mailing list to notify errors. Thanks.
errors in ed-0.4
I'm sure Antonio Diaz means well, but there are a couple of glaring errors in signal.c:
In sigwinch_handler(), there is an executable statement before a declaration (when TIOCGWINSZ is defined). That works in C++, but not in C.
In set_signal(), the non-standard flag SA_RESTART is used. This should be conditionalized, as it is not supported on all flavours of Unix (including QNX Neutrino); POSIX does not in fact require it to be defined.
excellent.
This is quite possibly one of the coolest projects I've ever seen announced on Freshmeat.
