Samuel, I have seen your next message, but it still may be helpful to 
have an example (for a case if you will meet the problem again).

These regexps will always fail under some conditions, since it is not 
strict markup. An example is emphasis terminated inside link target

Thank you, Ihor. Another reason why I have not tried to do it myself is 
that it is necessary to test behavior for users who customized markers. 
The change should not be fatal for them. I have not checked it with you 
patch yet.

I was considering some way to warn users if improper customization is 
detected (unexpected marker is noticed). It should be noticeable to make 
user aware of export issues but not too annoying.

Since this is known point of abuses, maybe stronger words are appropriate.

Do not change makers and do not add new ones to use custom markers for 
existing styles or to introduce new styles. Org syntax is not meant to 
be configurable and such modifications will not work with export. If you 
are interested in fontification of custom markup inside Emacs only, 
there are other ways to achieve desired effect.

In addition, I do not like the following phrase in the manual:

> To narrow down the list of available markup syntax, you can customize org-emphasis-alist.
