Only problem with actually committing the change would be that it may
encourage more people to use Trac for RFE's. On second thought if all
the "RFE without a patch, marking as invalid" comments aren't noticed,
maybe people won't notice one actually getting a fix, either.
Hmm. This looks like a slightly offset version of HRC, is that the case?
Actually, IRC is basically standard (standard + 0.0125MHz) but with
channels 5 and 6 offset. I guess, though, that since HRC is a slightly
offset version of standard (with channels 5 and 6 differently offset
from the others), we can say it your way because of the commutative
property. :)
Seriously, though, the definition provided in the patch is identical to
the definition of us-cable except for channels 5 and 6, so I don't know
if there's a more efficient means of representing IRC than with a whole
new 133-element CHANLIST array (or, for that matter, if we should even
worry about whether there is).
Well, Chris's post made me feel guilty for posting a reference to the
0.18.1 patch with an assurance that it would be easy to update to
different versions without actually doing the easy update myself, so I
reopened the ticket with an updated patch. I figure the time I spend
updating the patch will probably be less than the time people will spend
teaching users whose cable-companies use IRC to fine-tune channels 5 & 6
on the lists...
