No space after "*".

The indentation of the following lines looks odd after this patch; unless 
that's just an effect of TABs plus quoting, make sure they are reindented 
to line up with the new position of the opening '('.

Capitalize variable names when referring to the value of the variable, so 
ORIG; likewise elsewhere in this comment.  Single work "backslash".

"file name" should be two words, according to the GNU Coding Standards.

"occurrence"

Returning wrong results on insufficient memory doesn't make sense.  
Anyway, xmalloc always exits the program if there is insufficient memory, 
so you don't need any code to allow for that case.

Newline, not space, between return type and function name, so that the 
function name comes at the start of the line.

The comment didn't mention NULL as a valid argument, and it doesn't appear 
NULL can actually be passed to this function.  So don't include code to 
handle that case.

Spaces around "=".

No space before "++", but put the body of the "if" on a separate line.

No space after "*".  Space in the cast after "(char *)".

Space after ",".

As discussed above, not needed.

> +      for (j=0, k=0; j<=len; j++, k++)

Spaces around "=" and "<=".

> +	  if (orig[j] == ' ' || orig[j] == '\t') new_spec[k++] = '\\';

Put the "if" both on a separate line.

> +  else return orig;

Put the "else" body on a separate line.
