A TAB takes you to a specific TAB spot, default is one TAB stop every 8 characters in a line. So the conversion is not just 'replace TAB with N characters'. This is one of the issues with TABs, they aren't as predictable as people might think, especially when mixed with spaces or placed in any location other than the beginning of the line all by themselves.
It should not change the indenting, but that's with the assumption that the TABs follow the 8 character spacing. And that of course depends on how you are viewing the source. :^( -kto On Mar 2, 2012, at 3:04 PM, David Holmes wrote: > On 3/03/2012 3:12 AM, Kelly O'Hair wrote: >> I don't understand the question.
