This just converts the few DOS text files still in here to standard text files (line-endings),
removes all the trailing spaces on lines, removes all the trailing blank lines, and replaces
all the tabs (except in .zon files, where they seem to be common) with expanded spaces.
It's easy to confirm this is actually a non-change, except for whitespace:
* `git show -w` shows this commit as only removing 8 trailing blank lines.
This should make no difference to tbaMUD itself, but it will make working on these files,
especially with scripts and automated tools, much easier.
This is the base change for a set of other changes I will put up once/if this merges,
without this, the others are just too complicated to wrangle.
I am guessing some script or tool used upstream is doing an unsafe
search-and-replace for '@' with TAB, and accidentally changing these.
They seem to have been creeping into the repo for years.
I produced this fix commit automatically with:
sed -i 's|\t\([bcdgmnoruwyBCDGMRWY]\)|@\1|g' tba/*/*.*
...and then a few files' changes had to be undone.
I looked through all of the rest, and they look like correct fixes.
I also ran all the other letters, and they only make incorrect "fixes".
