Replace fails when Old and New are the same

[Christian Paz]

When you call the function Replace with the same character to be replaced and being replaced, there is an error.

I think there are two possible solutions, or comparing oldChar and newChar, or changing line:

while(pos=strchr(pos, oldChar))

by

while(pos=strchr(pos+1, oldChar))

in BInt BText::Replace(BChar oldChar, BChar newChar)

It could be great if we take advantage of this change to allow replacing strings as well as unit characters.

Thanks in advance,
Christian

First option is more efficient due it must do nothing in this case

Thanks to report it
