Because -e takes a file format as argument, and the file format for
pdflatex output is pdf2, not pdflatex.

I do not see such a huge difference.

At 26ea1e14966c

real	0m18,531s
user	0m13,952s
sys	0m3,168s


At 337ec5830a041 (the commit before):

real	0m16,335s
user	0m11,609s
sys	0m3,259s

So a bit more, but not that much.

Stable gives:

real	0m16,731s
user	0m11,244s
sys	0m4,251s

And current master:

real	0m33,165s
user	0m28,740s
sys	0m3,420s

So the cuplrit must be later (or it's a cumulative increasement).

I try to bisect myself.
