Update the handbook for 64-bit Linux emulation

Summary

The handbook currently says that 64-bit Linux emulation is not supported. It was added in 10.3. This is my suggested update to the wording.

Just one little nit, the rest looks good.

145

I would rephrase this to "On 64-bit machines, <filename> ..." so that the sentence does not start with the <filename> tag.

Reworded to avoid starting a sentence with a <filename> tag.

Great, thanks for submitting the update. I'll commit it later today.

There is no rule to avoid markup for the first word in a sentence. The only history of this was due to a buggy shell script that dealt with man pages and has not be used since Linuxdoc times a couple of decades ago.

For clarity, sentences should be written the way they are spoken. The original was better because it did not have that pause in the middle.

I would edit this sentence to avoid the passive wording, though.

<filename>/etc/rc.d/abi</filename> automatically loads the module for 64-bit support on 64-bit machines.

The "64-bit" redundancy could be improved.
