How much control over line breaks should I exercise in a formal letter?
I have a quote of the text of an email message, which includes a standard US-style phone number including area code. Right now it's breaking naturally right before the last four-digit group.
It looks funny to me but on the other hand, breaking before the phone number, which ends the sentence, looks pretty bad too. So I'd like to know what the standard or common convention is for this. Because this is a quote of an email message I can't fudge by, for example, putting parentheses around the area code. I have to quote the email verbatim.
What I could do is increase the indenting on the quoted text just enough to make the word wrap more felicitous but before I do that I'd like to understand what the convention is for breaking phone numbers.
I have a long-ish paragraph in the middle of the page, which ends with the word "up", and another paragraph below it on the page. Seeing that lonely word ending the paragraph bothers me, but maybe this is normal and I should convince myself to get used to it?
