Emphasis is applied by matching against a regular expression stored in the 
org-emph-re. I get

| org-emph-re is a variable defined in `org.el'.
| Its value is 
| "\\([         ('\"{]\\|^\\)\\(\\([*/_=~+]\\)\\([^     
\n,\"']\\)\\3\\)\\([-   .,:!?;'\")}\\]\\|$\\)"
| Documentation:
| Regular expression for matching emphasis.

which is way too complicated for my simple mind to wrap around without
some guidance. But the doc for org-export-with-emphasize says:

| org-export-with-emphasize is a variable defined in `org-exp.el'.
| Its value is t
| Documentation:
| Non-nil means, interpret *word*, /word/, and _word_ as emphasized text.

| Not all export backends support this.

so *words* are emphasized[1].

Can you write

        Select '=life= for the x variable.

instead? The quote is not part of the <code> block, but does that
make much difference? And if it does, a little postprocessing on the
HTML might be all that is needed[2].


[1] although after staring at it for a while and with the hindsight
provided by the org-export-with-emphasize doc, the part that goes [^    
specifically excludes spaces, tabs, carriage returns, newlines,
commas, double quotes and single quotes as components of words.

[2] You might try changing the RE (it is constructed in
org.el:org-set-emph-re()) - but regular expressions are very unforgiving
beasts: you forget one character or add one too many and the whole thing
goes to hell in a handbasket, faster than a bat out of hell - choose
your own cliche' :-)
