Hi Again --

Several people have provided corrections to my case conversion macro.  In order
that a correct version be available, I am reposting with the corrected version
of the macros.  They are:
----------------------------------------
map	^C	: ^W -- reverse the case of the current word
map	^C	: ^T -- reverse  the case of the current line.
map	^C	: a more elegant definition for ^T is
map	^C	: 	!!tr '[a-z][A-Z]' '[A-Z][a-z]'^M
map	^C	: but this trashes the screen display near the
map	^C	: end of the file in some cases :-(.
map	^T	0y$Pa^M^[-:s/./\~/g^M"0zy$dd@z
map	^W	lBi^M^[Ea^M^[-I ^[^d0^T-3J
----------------------------------------
Before :so'ing the above, convert the following characters:
	^ C	==>  <cntl> C	[or these lines can be discarded]
	^ M	==>  <cntl> M
	^ T	==>  <cntl> T
	^ W	==>  <cntl> W
	^ [	==>  <esc>
	NOTE: ^d **really** is a carat (^) followed by a lowercase d.

The ^W macro will reverse the case of the current word (the word that contains
the cursor).  The ^T macro will reverse the case of the current line.

Thanks to all of the people who sent me suggestions and bug reports.  I hope
that these two macros work better.

The alternate definition of the ^T macro [using tr(1)] causes vi to get
confused when the operation is done in the first line of a file that is less
than about 20 lines long.  The contents of the file is correctly translated,
but the screen is corrupted with duplicate copies of the last few lines of the
file.
