[PATCH] Headers filter: style

[Piotr Sikora]

Hey Maxim,

But "h" is used throughout the codebase for ngx_table_elt_t, which
makes this particular case confusing.

Also, "h" is used for ngx_table_elt_t regardless of whether it points
to a particular item or an array, so your argument isn't consistent
with the current style.

Best regards,
