Starting an entry with multiple line breaks splits the end of the first line by the number of line breaks

Diagnostic output

jrnl: v3.3
Python: 3.11.1 (tags/v3.11.1:a7a450f, Dec 6 2022, 19:58:39) [MSC v.1934 64 bit (AMD64)]
OS: Windows 10

Current Behavior

Run jrnl by itself, then, in your editor, add at least two line breaks and type a sentence. After you save, it will insert a single line break before the end of your sentence. The distance before the end is the number of prepended line breaks minus 1.

Expected Behavior

The entry shouldn't be cut off just because of prepended line breaks.

Repro Steps

• Run jrnl
• In your editor, press enter twice, then type "entry"
• Run jrnl -1
• You'll see something like this:

[2023-02-11 11:47:35 AM] entr
y

• Run jrnl
• In your editor, press enter three times, then type "entry"
• Run jrnl -1
• You'll see something like this:

[2023-02-11 11:48:04 AM] ent
ry

Other Information

I also tested this with the default stdin editor and saw the behavior. @wren reproduced this on a Mac also so it's not Windows-specific.
