One possible fallout can be that your c<space>c is really a c<tab>c, but while on display it looks like one single space. A <tab> moves the character to next tab stop.
Then why the gap between them is so less??
I don't understand..
But the first tab is intact!

So either it's a version that's different enough (GNU sed v4.2.1 here) or the characters you replace are really just multiple spaces. Try 'hexdump -C textfile' or use the sequence 'ga' in normal mode in vim to get info about the character under your cursor.

Hey 'hexdump -C file' helped me!!
Its indeed a tab.. Don't know why it is displaying in that fashion!! Smilie
Anyway thank you so much!! Smilie
