doc: update iojs.1 for man page

[yosuke-furukawa]

I checked man iojs but some options are missing like (--trace-sync-io, --strong_mode).
so I just updated iojs.1.

typo: fetaures -> features

[yosuke-furukawa]

@Trott Thanks. I will fix.

these options are generated by v8... I will try to report or pull request to v8.

@yosuke-furukawa I already did a CL about that a while ago.
It is here but was never reviewed.
@bnoordhuis maybe you know what I should do to summon a reviewer?

[targos]

LGTM btw

[Fishrock123]

Maybe I/O?

[Fishrock123]

Had been meaning to do this. LGTM otherwise.

[Fishrock123]

Had been meaning to do this also. LGTM minus the comment

[Fishrock123]

@yosuke-furukawa LGTM :)

[thefourtheye]

Listed twice with different default values.

[yosuke-furukawa]

ooops, this is also v8 document mistake....

[yosuke-furukawa]

fixed! PTAL @thefourtheye

[thefourtheye]

overapproximate weak closer or overapproximate weak closure?

[thefourtheye]

@yosuke-furukawa Sorry, I couldn't complete the review the other day. I left two more comments now. PTAL. LGTM 👍

[Fishrock123]

I wouldn't worry about reviewing the v8 options too much. They'll probably just be overwritten in the future anyways.

[yosuke-furukawa]

Yes, I agree @Fishrock123 .

I just output these options using d8 --help.
We don't need to correct these options directly.

LGTM

@yosuke-furukawa I guess you can land it after an rebase.

[yosuke-furukawa]

@silverwind Thank you!

[evanlucas]

Looks like the --trace-sync-io option is still not in the man page. The v8 options appear to have been updated though. Do we want to rebase this?

[yosuke-furukawa]

I feel this man page should be generated automatically. I will close this and I will send another PR ASAP.
