PDF never uses tabs and spaces for indentation. In a PDF file, typically
all words are placed using a drawing operator individually, the space is
made up by your eyes when see the file. While space characters exist in
fonts, they are practically never used. Often even inside a word there
are breaks, because of kerning corrections. When copying the data, the
PDF reader has to guess where the word breaks are and how the strings
belong together. Acrobat does a good job, but fails in this special
situation. Sometimes it even fails for a narrow running font and copies
the string without any word breaks.
Laura's method works, because pdftotext can simulate the PDF appearance
using spaces in the output. Maybe an OCR program with good layout could
also be used.
