 For now we have seen a way to parse blocks, but markdown also handles strong, emphasis and links. However, these tags can appear anywhere in a line.
 Hence we need to be able to parse these lines apart from the block itself : indeed a header can container a strong and a link.
 
-A very useful function in awk is `match` : it literally is a regex engine, looking for a pattern in a string.
+The previously introduced but very useful function `match` fits this need : it literally is a regex engine, looking for a pattern in a string.
 Whenever the pattern is found, two global variables are filled :
 - RSTART : the index of the first character matching the *group*
 - RLENGTH: the length of the matched *group*
 
 For the following, `line` represents the line processed by the function, as the following `while` loops are actually part of a single function.
 
-This way `match(line, /\*([^*]+)\*/)` matches a string surrounded by two `*`, corresponding to an emphasis text.
-The `*` are espaced are thez are special characters, and the *group* is inside the parenthesis.
+This way `match(line, /\*([^*]+)\*/)` matches a string (that does not start with a `&#42`) surrounded by two `*`, corresponding to an emphasis text.
+The `*` are espaced as they are special characters, and the *group* is delimited by the parenthesis.
 To match several instances of emphasis text within a line, a simple `while` will do the trick.
 We now only have to insert html tags `<em>` are the right space around the matched text, and we are good to go.
 We can save the global variables `RSTART` and `RLENGTH` for further use, in case they were to be change. Using them we also can extract the

+The while loop enables us to repeat this process as many times as this pattern is encountered within the line.

 We now can repeat the pattern for all inline fonctionnalities, e.g. strong and code.
 
 The case of url is a bit more deep as we need to match two groups : the actual text and the url itself.
