  * TclCopyAndCollapse --

- *	Copy a string and eliminate any backslashes that aren't in braces.
+ *	Copy a string and substitute all backslash escape sequences
  *
  * Results:
- *	Count characters get copied from src to dst. Along the way, if
- *	backslash sequences are found outside braces, the backslashes are
- *	eliminated in the copy. After scanning count chars from source, a null
- *	character is placed at the end of dst. Returns the number of
- *	characters that got copied.
+ *	Count bytes get copied from src to dst. Along the way, backslash
+ *	sequences are substituted in the copy.  After scanning count bytes
+ *	from src, a null character is placed at the end of dst.  Returns
+ *	the number of bytes that got written to dst.
  *
  * Side effects:
  *	None.
