Would it be worth adding this hard-won lore somewhere on a Wiki

Dear Simon, all,
I don't think logging a specific option on the Wiki is particularly
useful (maybe you would have a default editrc file), because, of
course, everybody has their own particular wishes. For example, aside
from the word-jumping Duncan suggested, I alway use zsh-like history
searching, so I like:
bind "^[[A" ed-search-prev-history
bind "^[[B" ed-search-next-history
Also, there are no de facto escape sequences, because special keys
(like function and arrow keys) have different sequences on different
terminals. A useful tip that may be useful to include in the wiki is
an easy trick that will help you find out your terminals escape
sequences. I usually just like to start an application that has no
editline or readline capabilities and press the keys. Telnet is one of
my favorite applications for this purpose.
Something that I would personally very much enjoy is a clear and
unmistakable warning from configure when editline is not found. After
installing libedit-devel (my ghci-6.10.1 finally has comfortable
editing now), I checked config.log; there's not even a mention of
libedit capabilities. Maybe a general summary at the end of configure
of all the optional capabilities that were or were not configured. As
an inspiration, look at gtk2hs' configure output.
Regards,
Philip
