This is an interesting problem. I've personally found visual-block
yank / put most useful in ASCII art, where true rectangular blocks are a
feature. I see some tantalizing hints in the visual.txt help file about
padded with whitespace or not, but I can't get that to work for this
type of change.
Faced with a problem like this, I'd probably write a program to do the
change (possibly within the editor :'a,'e ! perl -wne '...' -- or
possibly as a separate true script), but I might also find a way to
do it with marks and macros. Maybe something like this tail-recursive
thing:
:map ## maf;'b"aDddmb`a"aPj0##
Set up mark b at the start of the /subdir area, move to the start of
the /path;text area and start
f; find the ;, hopefully will error out at end
ma set mark a
'b jump to mark b (start of line)
"pD delete to end of line, stored in p
dd delete now blank line
mb set a new mark b
`a return to mark a (mid line, on ; )
"pP put buffer p
j0 move to start of next line
## recurse
(Untested.)
