@ -98,5 +98,13 @@ SOW must match:
Not only that, this combination is key,
either it has to be the start of the string
or there has to be at least something which is not a symbol char.
With out the last condition "eexample" would match "\\\<exaplme\\\>"
With out the last condition "eexample" would match "\\\<exaple\\\>"
as the iteration of `regex_match()` reaches "example".
From a more practical perspective:
``` C
\<myword\>
// Must match
"myword"
" myword"
```
