Correct quotation marks for LaTeX
Fix quotation characters

Use ASCII quotation marks rather than fancy Unicode quotation marks,
as VCF files need straight ASCII ones and the fancy ones disappear
during TeX processing anyway.

Also remove excess spaces from ##INFO=<..., Source="foo", Version="bar">
example.
Describe the 28 byte empty BGZF block used as an EOF marker
Clarify EOF check with random access vs streamed files.

Document the BGZF EOF marker block

Merge branch bgzf_updates of git://github.com/peterjc/hts-specs

Further clarify: that (although it's unlikely) EOF markers can appear
in the middle of BGZF files and are insignificant there; why warning
early is useful and that this need not be in an API's open() method
but merely soon after that's invoked; what tests suffice.
Added an optional tag for storing the mate/next segment CIGAR string.
